Details:
LM3886 is a prestigious high-performance audio power amplifier integrated circuit in the United States (NS), with a maximum output power of up to 68W. The timbre is vivid, noise, and distortion are very low, and the protection function is relatively perfect and the performance is stable. Once the LM3886 introduced a rave reviews, it soon became the configuration of amplifier circuits for large and medium power HIFI audio amplifiers and high-fidelity active monitor speakers. This IC audio enthusiast can be described as nobody knows, no one is not aware of; despite the rapid development of audio technology over the years, but the two IC because of performance, excellent sound quality, excellent, is still widely used, enduring. The well-known American audio manufacturer Le Lin has the LM3886 as the core of the enlarged price machine. It can be said that the LM3886 is one of the audio power amplifier ICs that every audiophile must play and often play.
1)LM3886TF, NE5534, OP07
2) The resistor uses a five-ring metal resistor, and the main loop uses a five-ring metal film resistor with an accuracy of ±1% to ensure a good signal-to-noise ratio.
3) The main filter electrolytic capacitor uses the famous gold NOVER audio dedicated capacitor, capacity 10000UF/50V*2, to ensure a steady stream of powerful power support.
4) PCB adopts 1.6mm thick double-sided plate, 2.0oz thick copper, and spray tin process to ensure good current performance. First-class PCB quality
5) Add special advanced UPC1237 horn protection circuit to effectively control the start-up impact sound and make your speaker more secure.
6) The layout of the entire circuit board is very rigorous and reasonable, and the overall PCB trace uses a point grounding method. The power amplifier board is stable and reliable, and has a large output power; the sound is mellow and the sound field is open. Strong three-dimensional sense, strong and stable low-frequency sound, signal-to-noise ratio is very good, a wide dynamic range; clear details, excellent transient response, play a variety of music to cope with, in the family&x27;s playback environment has a very good performance.
6) This board is very easy to connect, as long as the configuration of a few parts can be assembled into a beautiful sound stereo HIFI integrated power amplifier, ideal for audio enthusiasts to use. It is also possible to replace the more suitable and better components with your understanding of the circuit and enjoy the DIY process. (Absolutely worth a try, the effect is very good)
7) The pre-stage op amp is powered by DC servo, and the sound is better
